To all whom it may concern:

Be it known that 1, JOHN B. ANTON, a citizen of the United States, and residing in the borough of Monongahela, in the county of lWashington and State of Pennsylvania, have invented or discovered new and useful Improvements in Car-bid Miners Lamps, of which the following is a specification.

My invention consistsin a new and improved carbid miners lamp.

The object in View is the provision of a lamp which will be of simple, compact, durable and inexpensive structure, wherein the gas Will be presented to the burner tipat uniform pressure, in a cleansed and cooled condition, free from water and mechanical impurities, and wherein the reflector may be I placed, and the burner tube and tip cleansed.

In the accompanying drawings, Figure l is a side elevation of my improved lamp; Fig. 2 is a central vertical section oi' the same; Fig. 3 is a horizontal section along the line III-III in Fig. 1, and 4 is a vertical section along the line IV IV in lhe following is the drawings.

A is the Water tank provided with a filling port 1 having a hinged closure 2. From the bottom of tank A depends a threaded neck 3 into Which is screwed the correspond ing threaded neck of the carbid tank B.\ A admits water a detailed description pt from tank A to tank B.

C is an annularinctal cup, harine its inner end closed, set into the interior or the tank A and having its open end fixed in the lront wall of said tank. T he inner, closed end or the cup C is connected by the elbow tube (5 with the carbid tank, the lower endo't said tube extending through the bottom of tank A at one side of the tube 4, and the upper end of tube 6 extending through the closed end of cup C, preferably at oncside of'the center thereof.

7 is afilter of felt, or some otherabsorbent, material, in annular form, slipped up on the tube 4; against the bottom of ti e tank A, and

' held in place by the spring vasner iv. The- .gas arising from the generating chan'ibe into the tube 6 is thus filtered o portion of its impurities. x

The open end of cup (1- ided with. "irted with the f the and or.

annular wall of the cup by means of annular shoulder 10 which bears against the wall of tank A and enables the cup to be rigidly soldered or otherwise fixed in place. The annular wall of cup C is provided with a screw thread 11, which may be conveniently pressed in thesheet metal of the cup.

D is the reflector provided with a polished concave-d reflecting face 1 surrounded by afiaring annular flange 13. v

lat is an annular neck concentric with the reflecting face and extending rearwardly. Said neck has a thread impressed therein, so as to screw into the cup C. Surrounding the base of the neck 1% and merging into the flange 13 is a narrow shoulder 15, and 16 is an annular gasket oi rubber or other suitable .material, so that when the reflector is screwed up into-the cup, as shown, a gas tight-joint is made between the cup and the reflector.

A. burner tube 17 extends axially through the reflector face 12, and 18 is a burner tip mounted in the outer end of the burner tube. The gas ascending from the ca'rbid tank 13 is-partially cleansed bythe lilter T and enters the interior of the cup C through the tube 6. The generation of gas is at a. varying ate, so that the gas does not pass. through the tube 6 at a constant pressure, and, ii the burner tip were ted directly from the tube 6, the illuminating flame would flicker and Vary-in intensity. However, the interior of the cup C provides a chamber of relatively great capacity wherein the gas has an opportunity to expand and, as a result,

the gas pressure at the tip madeuniform.

Th1: oallling the gas in the interior of the cup rauses the mechanical impurities carried by the gas, such as small. part cles of.

slakcd *arbid. to be precipitated, and thus pix-events clogging of the burner tube and tip. Again, the inward protrusion of the can (5 \Ylllllll the Water tilled tank .132. water cools the walls of said cap and thus tacili tates the precipitation of the moisture car- 'iiedby the gas, and, by drying and cooling the gas, increases its illuminating value. Q'Tlie socketin'g of the reflector in the cup 5 contained in the water tank enables the reflector to be located close up against the front wall of the tank out of the way and less likelyto be bumped against'hard objects -and bent out of shape when the lamp is v worn on the miners hat or under other conditions. v

When the reflector becomes so damaged as toimpair'its usefulness, it may be unscrewed and a new one, obtained at slight expense,

substituted.

When: the burner tube or tip becomes clogged, the reflectormay be unscrewed, the tip pushed out of the tubeand the parts cleansed; j

Theconstruction is very simple, inexpen sive and ea'sy'to manufacture, and forms a 1 compact, strong, durable, and; attractive structure.

What I-desire to claim is-:-'-

. 'In combination with the water tank and the carbid tank ofa carbid lamp, an internally threaded .cup socket having its open endfixed in the'front wall of the water tank and bodily extending into the interior of I said tank, a gas tube connecting said carbid tank with the inner end of said cup socket, a reflector, a burner fixed in the axis of said reflector, and an externally threaded. an- -nular neck concentric with'and extending rearwardly from said reflector and screwed into said cup socket, substantially as described.

2. In combination with the water tank and the carbid tank of a'carbid lamp, an internally threaded cup socket having its 40 open end fixed in the front wall of the water tank and bodily extending into the interior of said tank, a gas tube connecting the carbid tank with a point in the inner end of the cup socket at one side of the center of the latter, a reflector, a burner fixed in the axis of said reflector, and an externally threaded annular neck concentric with and extending rearwardly from said reflector and screwed into said cup socket, substantially as described.

3. In combination 'with the water tank and the carbid tank of a carbid lamp, an i internally threaded cup socket having its open end fixed in the front wall of the water tank, and bodily extending into the interior of said tank, a gas tube connecting the carbid tank witha point in theinterior end ofthe cup socket at one side of the center of the latter, a reflector, a burner of less capacity than said tube fixed in the axis ofsaid reflector, and an externally/threaded annular neck concentric with and extending -rearwardlyirom said reflector and screwed into said cup socket, substantially as described.
